KNITTED FABRIC AND Mn'rirop on MAKING THE sans.

Original application led November 6, 192V2, Serial No. 599,402. Divided' and this application nled November 6, 1924.

This specification is a division of that filed by me Nov. 6, 1922, Serial Number 599,402, now Patent #1,608,194, and concerns the product i. e. the stocking made on the ma.- cliine oflsaid application. v

In the accompanying drawings Figure l is a view of a portion of the split fabric which appears in the stocking in the 'foot and above the heel.

Fig. 2 is a diagrammatic view of the stockmfr.

Fig. l is a diagrammatic perspective View showing the conditions when the instep yarn guide A is returned to feeding position after the heel is knit and the split fabric above the heel is to be knit.

Fig. 8 is a diagrammatic plan view showing the instep'yarn being knit in with the main yarn, preparatory to being clamped and cut to terminate split fabric above lthe heel.

Fig. 9 is a diagrammatic plan View of the instep yarnclamped and severed while circular knitting above the split fabric above heel is performed with main yarn.

The split foot fabric shown in Fig; 1 is knitwith the main and instep yarns shown respectively in dark and light loops in said ligure.v The instep yarn remains in work until the heel is to beformed, whereupon the following actions take place. The instep yarn is raised out of feeding position to dotted line position shown at A', Fig. 3, but

remains tied to the fabric as shown in Fig. 3l

prior Serial N o. 748,180.

atft'. This action is performed by moving the yarn finger A radially outward from full line position a to dotted line position a and side the needle row. The yarn when raised` as just described is controlled by a spring detent 80 and guard plat'e 80 and slot 80 of plate 80 and held so as tov avoid .beingl clamped bythe clamp 82 and severed by the of the needle row and cutter 80", so that as just stated, this instep yarn remainstied to the fabric, at the point t, and will be allowed to iioat. 'The heel is now knit with the main yarn.

, When the heel pocket is finished and the split portion of the stocking above said pocket at the back ofthe stocking 'is to be knit, that is, the po/tion corresponding in location to what is known as the high splice, together with the part above the instep, the

Ainstep yarn fingeris again thro-wn into work the fourth and fifth needles from the end of the row, which will knit on this stroke (clockwise) and as this stroke continues, the yarn will wrap around the outside of the needle row, see Fig. 5, and here it will be noticed that this instep yarn ^will be knit into the fabric with the main yarn going in,

from the main yarn linger B. This knitting .in 'of these two yarns jointly will take place it is knitted in at the fourth or fifth needle,

as the case may be. This how appears, of course, on the inside of the fabric. This inplace in Fig.y 8;A

c'eed to make that however,

step yarn, having been knit into the section of the split fabric above the heel, that is, that section whlch is knit with the main yarn from finger B, and this havin been locked in place, the anti-clockwise stroke takes place and the length of yarn which is wrapped 'around the outside of the column of idle needles, see Fig. 5, will be taken up by the yarnUtake-up mechanism and thus drawn back through the feed linger A. On the next clockwise stroke this instep yarn will sproportion of the split fabric around the front of the ankle, and this 'will take place first at the left-hand knitting cam of the front o r-- second set of cams, and then at the right-hand cam on the next anti-clock,- wise-stroke, and so on. While these actions p are taking pla-ce, the portion above the heel will be knit by the main set ofV cams and the heel and toe needles Aat the main feed B.

It will be understood, of course, that up to vthis time, following the completion of the heel, and while'the first clockwise stroke is taking place, as shown in Figs. 4 and 5, the front or second set of cams are inoperative.

This locking in of the instep yarn takes place substantially at the point s as indicated in the diagram ofthe stocking, Fig. 2.

The auxiliary or instep yarn finger, when feeding, at all times lies just outside the needle row. The split fabric portion above the heel pocket having been knit, as just described, the instep yarn guide is lifted from its feeding position as shown in Figs. 6, 7, 8 and 9. yIn this lifting action, the aulxiliary yarn feed lfinger is not given first a radial outward movement, as in the case when be ginning to knitthe heel, as now it is not intended to' leave, this yarn tied- 'into the fabric, until it is brought into xwork again, but it is intended to sever and clamp it within the needle circle. Tt is also intended, to lock it into the upperedge of that portion ofthe split fabric which lies above the heel by knitting it in together with the main yarn and this is the-action taking Tn the diagram of the stocking, the shaded portions arethose knit with the cotton yarn throughout the foot and above the h`eel,'and the portion s shows vthe silk or other instep yarn, and the line of stitches where the instep yarn is locked in'to the dark portion of the split fabric, as indicated at s2. l

Tn this lifting action just mentioned, the yarnnger is raise directly from its feeding position, vas indicated in Figs. 6 and v7, and it will lay first over some of the beards f and as the movement continues clockwise, the

yarn will pass in between the needles at some distance back from the traveling point where it is tied into the fabric and this stretch of yarn `will lay against the outer side of the stems and under the beards and will be in position to be takenby these 'needle row, and from ythere'the yarn will'y extend out between the needles and along the outside of the stems of the few mentioned, see z3 to e4, Fig. 8, to be knit in as above described. The continued movement ina clockwise direction will cause thisyarn to bey carried under a spring wire' clamp 82 `and then to a cutter 8()b at the edge of the notch 8 3in the base plate 80 where the yarn will be severed, .but the cut end will ,be held under the clamp until this clamp is relieved from pressure and releases the arn. A. l

The instep yarn lingerv is pivotally mounted at 7 8 It has a bifurcated base .portion through the depending ends of which they pivot extends and it is pressed by a spring '84 which tends constantly to move the yarn finger to its lowered position. It is. operated by a lrod 84.extending from the upstand- V ing ear 811 of its base portion.

When one of the main yarns 1s lifted out of work, 1t is carried beneath a clamp 85 'and a shear .blade .85", which latter severs it, and the cut end is held by the said clamp, as 1n Patent 1,608,194, Nov. 23, 1926, of which the present specification is adivision.

This clamp and shear blade are both oper-4 ated by a vertically extending rod, spring vpressed downwardly as at 86, and raised by a lever 86 bearing on the underside ofpin 86c operated by a rod 861'. The spring pressed plunger or rod 86, is connected by a pin 86b with the movable shear blade 85 like in said patent whichl is pivoted to the standard at 87 and a-second pin' 86d connects the vertically working plunger with the clampv85a so that both will be lifted when the pluanger is raised to allow the yarn to pass beneath them, andv thereupon they both fall together to sever and clamp the yarn.

lin Figs. 2 and 9, I shown an arm or finger 88 extending near the instep yarn guide. This will catch the yarnl as 1t is raised out of work and assist in directing it as shown in this Fig. 8. This linger' isan extension of the bearing 88 for the s ring clamp 82. This bearing is carried y a lever 88" pivoted to the post 89 as in said patent extending up from the shear and clamp plate and this. lever is operated by a rod 9 0 to lift the bearing and thusgraise the spring wire clamp 82 to release the instep yarn.

Fig. 9 shows the instep yarn severed and clamped. The end shown at y is the severed extension of the portion which is knit in with the main yarn at 225 Fig. 2.

I claim:-

l. A split foot stocking having an instep yarn knit in with the yarn from the main feed at the end of the heel gore to be thereby locked in place, said instep yarn being continued intact in knitting split fabric at the ankle portion at the top of the instep, the main yarn forming the split fabric above the heel, said instep yarn being thereafter knit in With the main feed yarn, and then severed, substantially as described.

2. A split foot stocking having the instep yarn knit in with the yarn from the main feed at the end of the heel gore, and thereby locked in place, and thereafter continued intact in the split fabric ankle portion above the instep, the main yarn forming the split fabric ankleportion above the heel.

In testimony whereof, I aHX my signature.
